SEXUING-MACHINE NEEDLE PLATE.

Application filed June 23, 1921.

T 0 all whom it may concern:

Be it known that I, EDWARD J. Rooms, a citizen of the United States,residing at the city of Anacortes, in the county of Skagit and State oflVashington, have invented certain new and useful Improvements inSewingMachine Needle Plates; and I do hereby declare the following to bea full, clear, and exact description of the invention, such as willenable others skilled in the art to which it appertains to make and usethe same.

The present invention relates generally to sewing machines, such as areused for sewing leather, rubber and similar materials, and the inventionaims to provide a needle plate cap or support and a double ended needleplate mounted thereon, and reversible for use in sewing leather andrubber, said plate having a cutter for channeling or slitting theleather, and means being provided for holding said plate in eitherposition.

It is the object of the invention to provide a novel double needle platefor use in sewing both leather and rubber, with novel means for mountingsaid plate and retaining it in either position.

With the foregoing and other objects in view, which will be apparent asthe description proceeds, the invention resides in the construction andarrangement of parts hereinafter described and claimed, it beingunderstood that changes can be made within the scope of what is claimedwithout departing from the spirit of the invention.

The invention is illustrated in the accompanying drawing, wherein Figure1 is a plan view of the device; and

Fig. 2 is a section on the line 22 of lldounted on the needle plate capor support 3 is an elongated double-ended needle plate or bar 4, whichis pivoted intermediate its ends on the cap or support 3 by means of apivot bolt 5, permitting said plate or bar 4 to be turned about avertical axis end for end. The plate 4 is provided adjacent to each endwith a needle slot 6, for the passage of the needle, and one end portionof the plate is plain for sewing rubber, while the plate is providedthereon near the other end portion with a cutter 7 beyond one end of thecorresponding slot 6, for channeling or slitting the leather.

Specification of Letters Patent.

Serial No. 479,817.

Thus, in sewing leather, the plate 4 can be turned to bring that endportion thereof having cutter 7 into position for cooperation with theneedle, whereas when rubber is sewed, and the same is not to bechanneled or slit, then, the plate 4 is turned around to bring the plainend portion thereof into position. The needle plate is readily turnedaround, for conveniently changing the device for sewing either rubber orleather.

In order to retain the needle plate in either position, a catch isprovided, including a leaf spring 10 secured to the under side of thecap or support 3 by means of the bolt 5 and projecting to the rear endof the support and h as a button 12 sliding through the support for theengagement of the thumb or finger to depress said spring. An upstandingpin 9 is secured to the spring 10 between the ends thereof and slidableupwardly through an aperture 10 in the support 3. The plate 4 hasapertures 11 between the pivot 5 and ends of the plate, for thereception of the pin 9. Thus, when the plate is turned to eitherposition, the pin 9 will snap upwardly into the corresponding apertures11, and by depressing the free end of the spring 8, the pin 9 isretracted, to permit the plate 4 to be turned around. The change istherefore made quickly and conveniently.

Having thus described the invention, what is claimed as new is 1. Areversible needle plate device for a sewing machine embodying a support,a double ended needle plate bearing on the support, a pivot memberengaging through the support and mounting the needle plate for turningmovement to bring either end portion into position for sewing, and aspring catch at the under side of the support engaging said pivot memberto be held in position and having means engaging upwardly through thesupport to engage said plate for retaining it in either position.

2. A. reversible needle plate device for a sewing machine comprising asupport, a double ended needle plate bearing on the support, a pivotmember pivoting the intermediate portion of said plate on said supportso that either end of the plate can be moved to operative positionbeyond one end of the support, a leaf spring secured to the under sideof said support by said pivot s v I? In testimony whereof I have signedmy name to this specification in the presence of 10 two subscribingWitnesses.
